PICKER ARM AND ROLL.

SPECIFICATION forming part of Letters Patent No. 690,000, dated December 31, 1901.

Application filed June l5, 1901.

To all whom it may concern.-

Beit known that LVILLIAM WATTIE, a citi'- zen of the United States, residing at Worcester, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Picker Arms and Rolls for Looms, of which the following is a specification.

My invention relates to improvements in ro picker arms and rolls for looms; and the object of my invention is to provide improved mechanism for adjustably securing to the picker-arm the support or collar on which the picker-roll is mounted.

My invention consists in certain novel features of construction of myimprovements in picker arms and rolls, as will be hereinafter fully described.

Referring to the drawings, Figure l is an edge view of a picker-arm with one roll thereon embodying my improvements mounted on a shaft looking in the direction of arrow ct, Fig. 2. Fig. 2 is a side view of parts shown in Fig. l looking in the direction of arrow b, same iigure. Fig. 3 is a section on line 3 3, Fig. 2, looking in the direction of arrow c, same figure. Fig. 4. is a sectional view of a detached part of the mechanism shown in Fig. 3. Fig. 5 is a plan view of the detached part shown in Fig. 4 looking in the direction of arrow d, Fig. 4.. Fig. 6 is an edge view of one end of the picker-arm, taken at a point indicated by line 6 6, Fig. 7, looking in the directionof arrow e, same figure; and Fig. 7 is a plan view of the part shown in Fig. 6 looking in the direction of arrow f, same figure. Figs. 3 to 7, inclusive, are shown on an enlarged scale.

In the accompanying drawings, l is a driven shaft.

2 is a picker-arm centrally mounted and secured to the shaft 1, in this instance by a spline or key 3.

At each end of the picker-arm 2 is an elongated transverse slot or opening 4. The slot or opening 4: is surrounded on one side by a raised portion et', which is provided with teeth or ridges 5, arranged in parallel rows, as shown. A bolt 6 extends through the slot 5o 4 and also through a bushing or sleeve 7.

The head 6 of the bolt 6 bears on the outer end of the bushing 7 and has a iin 6 thereon,

Serial No. 64.640. (No model.)

which extends into a recess 7 in the bushing 7 to prevent the bushing 7 from turning on the bolt. The surface of the inner end of the bushing 7 is provided with teeth or ridges 7 arranged in parallel rows and adapted to engage with the tooth portion 5 around the slot 4. A roll 8 (only one roll is shown) is loosely mounted on the bushing 7 and is held 6e in position thereon by an annular shoulder 7" on the bushing 7 and the head 6 on the bolt 6. A nut 9 on the bolt 6 secures the bolt in the slot 4 and binds the bushing 7 to the toothed part around the slot 4, and a check- 6 5` nut 10 holds the nut 9 in place. The elongated slot 4 permits of adjustment of the bolt 6 to change the position of the bushing 7 and roll 8, as desired.

It will be understood that the details of 7o construction of my improvements may be varied, 'if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the picker-arm having a slot or opening therein with a raised portion around said slot or opening, said raised portion being provided with a toothed or ridged surface, a bushing or sleeve having 8o a corresponding toothed or ridged surface to engage the teeth or ridges on the raised por tion of the picker-arm, a roll loosely mounted on said bushing, a bolt for securing the bushing to the arm and means interposed between the bolt and bushing to prevent the turning of the bolt with respect to the bush ing.

2. The combination of a picker-arm have ing a slot4 or opening therein with a toothed 9e or ridged surface around said opening, abush; ing or sleeve having a toothed or ridged surface to engage the corresponding surface of the picker-arm around the opening, a roll loosely mounted on said bushing, a bolt pass'- ing through said bushing and secured to the picker-arm, said bolt having a fin to engage the bushing to prevent relative movement between the bolt and bushing.
